In the next few days of attacking, Owen can be said to be unhurried and impatient, and completely showed the level that a veteran driver of the black iron rank should have.

In seven days, the results of three rounds of siege battles made Du Yuanzhi's mood more and more solemn.

Repelled the latest round of enemy siege and walked back to the combat conference room with a quick walk, Du Yuanzhi's first sentence was......

"The other side is deliberately consuming our resources to defend the city!"

At this time, Du Yuanzhi was basically able to determine that Aowen still had a back hand.

After the resources in their city have been consumed, the other party's killer weapon may be used!

Such a means can be said to be a proper conspiracy.

The whole purpose is on the surface, but you can only move on.

Unknown hole cards can be unsettling.

Hearing this, Guo Zhen's two eyebrows were directly twisted into a ball.

"If the reinforcements from Oasis City and Xiyuan City want to rush here, it is estimated that it will take about a week, if they really can't withstand it, then we can only do it first!"

In this regard, Du Yuanzhi nodded, agreeing with Guo Zhen's words.

And at the same time, the other side......

Owen, who has fought three siege battles in a row, is still calm.

Although his army had suffered significant losses during the week's attack, it was well within his reach.

Since there is going to be an invasion war, it is obvious that this bit of psychological preparation is still necessary.

As long as he can successfully break through the city in front of him, he can win the invasion and plunder the resources and population of the city.

In such a large city, there are 300,000 or 400,000 people in it, right?

Such a large amount of cheap labor is enough to make the development efficiency of his civilization even more efficient!

Thinking of this, Owen pondered for a moment in his heart, calculated the time, and then turned his head to a guard beside him and said......

"Pass the order, rest for a day tomorrow, and start the day after tomorrow to carry out a continuous siege!"

There is no doubt that there are two distinct advantages to being a defender......

The first advantage is the towering city walls.

And the second advantage is the reinforcements in your own territory!

Owen saw the wolf smoke burning on the head of the high ridge city wall, and after receiving the signal from the rear, he calculated the time, and the reinforcements on the opposite side should have been halfway through.

After consuming a few more waves of resources to defend the city on the opposite side, it was almost time for him to move seriously.

Now let's turn to Spiegel.

Since the Europa player invaded, Luo Ji had undoubtedly received a number of flying pigeon biography from Kaolin City.

He had a rough idea of the situation at the front.

An infantry unit composed of a large number of shield soldiers, characterized by a balance between attack and defense, is perfect for fighting a war of attrition.

And that's obviously the main purpose of that Europa player.

Use a large number of shield soldiers to carry out continuous sieges, consume the defense resources of his Gaoling City, and then see the opportunity to break the city in one go.

This kind of method can be regarded as a typical yang conspiracy, and it is impossible for Du Yuanzhi not to see it.

So Luo Ji is not particularly worried.

Reinforcements from Oasis City and Xiyuan City are already rushing to Gaoling City.

The reinforcements of the two cities, together with 4,000 troops, plus the advantage of the city wall, it is not so easy for that Owen to take advantage.

And, even if it really comes to the point of last resort, they are not without hole cards.

The fighting on the western border is undoubtedly continuing.

After a day's rest, the siege army under Owen's command decisively launched a continuous siege.

One, two, three......

The onslaught of the Europa army did not give them a respite at all.

Outside Gaoling City, a large number of corpses have piled up.

And after a few days of sun exposure, it gradually emitted a disgusting stench.

Maintaining such a rhythm of battle, after five consecutive days of siege, Owen, who felt that the war of attrition had almost been played, decisively opened his hole cards.

Looking at the black Europa army outside the city, Guo Zhen on the wall, his face was already difficult to see.

"Do these invaders still have so many troops in their hands?!"

Although he couldn't come up with an accurate figure based on visual inspection alone, after so many days of siege, the opponent's strength was still at the level of seven or eight thousand, which already explained a lot of problems.

At the same time, in the opposite military formation, there were four more chariots filled with metal armor plates.

Just by looking at it, you can clearly feel the amazing defense of the other party.

In the sound of the high-pitched attack horn, a siege battle that has been gathering momentum for a long time is decisively started!

A large number of Europa soldiers pushed the four chariots towards the gate of Kaolin City.

Looking at that posture, the other party is probably planning to use that chariot to crash into the city gate!

Du Yuanzhi wanted to stop it, but the person who created the armored combat vehicle was obviously mentally prepared to let these four combat vehicles withstand all the firepower from the beginning.

The pieces of armor on top are simply thick and scary.

In the face of the continuous fire of the three-bow bed crossbow and the return artillery, although the four armored fighting vehicles were beaten beyond recognition, they still withstood the overwhelming firepower and stubbornly pushed forward.

"General, go and guard the city gates!"

Hearing Du Yuanzhi's shout, Guo Zhen, who was dressed in military uniform, had already rushed down the city wall quickly.

The previous ten days of attrition were fought, so that the defending troops of Gaoling City consumed a large amount of resources to defend the city, and now the firepower of this battle is not as fierce as before.

This is undoubtedly an opportunity for the soldiers of Europa.

After closing the distance to a certain point, they decisively began to push the ironclad car to crash into the gates of Kaolin City!

At this moment, an entire city gate was slammed into a rumbling sound.

The opportunity to break the city can be said to be imminent!

However, at this moment, the unexpected happened.

Under the repeated collision of the armored vehicles, the closed gate of Gaoling City began to rise slowly.

This made Owen, who was directing the siege in the rear, frown slightly.

"On the other side, is this planning to take advantage of the limited space in the city gate area to fight with me in a white-handed battle?"

As the thought arose, a sneer crossed Owen's face.

If that's the case, then it can only be said that the other side is too naïve.

His four ironclad cars are fully capable of rushing into the city in one go! Trying to trap him in the gate area is a dream!

And just as Owen was thinking this, a roaring explosion suddenly came from inside Gaoling City!

Then, before those Europa soldiers could react, a powerful impact force directly hit the front of the ironclad car!

The front of the armored car, which was covered with armor plates, was almost destroyed on the spot.

Even a whole ironclad car was blasted out.

At that time, the soldiers who were pushing the ironclad car in the back were even more unlucky, but they were knocked out and flew out, which was lucky.

Many soldiers were killed by the impact and vomited blood.

The amazing scene made the battle at the city gate fall into a deathly silence in an instant!
